. GUN CARRIAGE.

Application filed October 24, 1925, Serial No. 64,563, and in GermanyOctober 24; 1924.,

In the carriage according to the invention the central axle piececonnecting the wheel axle trees forms a separate part which can beadjusted to assume different positions relative to the axis of thewheels and in one limiting position coincides with this axis to form astraight axle tree. The length of the lever arms connecting the centralmember is altered, as required, by relatively displacing this memberwith respect to the axle trees about pins disposed eccentrically to theaxes of the said trees, or the carriage axle and the axle trees maybeconnected by vertically disposed guides so as by suitable means to beplaced at different distances apart and secured therein.

The arrangement according to the invention enables an inclined positionof the wheels to be compensated by the separate adjustment of the twoaxle trees and has also the further advantage that the firing heights ofthe gun can be altered, as re-' quired, within certain limits withoutessentially changing the position of the centre of gravity of the gunrelatively tothe wheel axle so that the stresses on the trail are notmaterially altered.

The accompanying drawings show examples of construction according to theinvention in which Figures 1, 3 and 5 carriage axle in the position forhigh firing with different means of connecting the axle trees with themiddle axle piece.

Fi ures 2, 4 and 6 are views correspond- 23 mg to carriage axle in theposition for low firing.

Figures 7 and 8 show respectively in rear and side elevation a guncarriage an gun adjusted according to Figure 1 for high firing.

Figure 9 is a rear elevation of the gun carriage and gun in the positionfor low firing according to Figure 2.

Fig. 10 is a side elevation of the gun carriage and gun in the positionfor lowfiring according to Fig. 2.

The carriage axle consists of two axle trees a and the middle axle piece7) connected with the carriage.

In the construction shown in Figure 1, each axle tree a carries a pin aeccentrically arranged on a vertical arm a. This pin is represent a partof the Figures 1, 3 and 5 of the parts of the pivoted in an upwardlyprojecting arm I)", provided at each end of theaxle piece 6, and thepins are secured by nuts a screwed on the threaded endof the pins. Inthe teas-gas position for high firing represented in F i5.

ure 1 the axle tree a engages. by means of the claw-shaped end a of itsarm a in a notch 6? provided in the'axle piece 6 and thereby preventsany lateral displacement in the hollow axle tree are inserted in borofthe relatively rotatable parts a and b. The arm I). is prolonged upwardsabove the.

ings of the arm 7) and prevent any relative radial displacement of theparts a and. b

which are swung together about the axle trees.

The axle piece bis adapted to be moved.

laterally in the carriage but'is prevented from rotating relatively tothe said carriage.

In-contrast to the construction shownin Figure 1, in which a straightaxle is formed for high firing, in Figure 3 the axle tree a is displaceddownwards relatively to the middle axle piece Z). For high firing thesaid axle piece is cranked upwards, for low firing (Figure 4) it iscranked in the manner previously described. I

In the constructions shown in Figures 5 and 6 any required firingbetween two limiting positions can be obtained.

The axle tree a carries a downwardly projecting guide bearing a with ascrew threaded spindle 0 rotatably arranged there in. The head I) of theaxle piece 1) slides in the dovetailed guide of the bearing a andco-operates with a screw-threaded spindle.

a rotatable by a hand-wheel 0".

In this construction the axle piece 6, in

order to increase the distance from the ground when travelling, ispreferably rotatably mounted in the carriage; this arrangement couldobviously be applied also to the axles in the previously describedconstructions, in order, by swinging the whole axle, to be able to setthe gun for still higher firing.

It is obvious that many changes may be made in the disposition and formof the members connecting the central axle carrying the gun carriageWith the Wheel axle trees Without departing from the scope of theinvention.

I claim:

1. A Wheeled guncarriage for setting the gun at different firingheights, axle trees for said Wheels, an axle piece carrying sai'd' guncarriage, pins eccentricallyconnected with said axle trees and armsInounted on said axle piece and adapted to be swung aboutsai'd pins.

2. A Wheeled gunca'rriage' for setting the gun at different firingheights, axle t're'esfor said Wheels, an axle piece carrying said guncarriage, pins eccenti'ically connected with said axle trees and armsmounted on said axle piece and adapted to be swung about said pins, inone limiting position said axle piece being in line with said axletrees.

3. A Wheeled gun carriage for setting the gunat different firingheights, axle trees for said Wheels, an axle piececarrying said guncarriage and rotatably mounted therein, and means for adjusting andsecuring said axle piece at different positions relatively to said axletrees.

' 4:. A Wheeled gun carriage for setting the gun at different firingheights, axle trees for said Wheels, an axle piece carrying said guncarriage, an arm secured to each of said axle trees, a pin secured" toeach of said arms and arms mounted on said axle piece and adapted to beswung about said pins.

In testimony whereof I have afiixe'ct my signature. I
